IMPROVED GAP FOP. PRESERVING-JARS- TO ALL WHOM 11 MAY CONCERN:

Be it known that I, JOSEPH BORDEN, of Bridgeton, Cumberland county, NewJersey, have invented an Improved Cap for Preserving-Jars; and I dohereby declare the following'to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawing, and to theletters of reference marked thereon.

My invohtion consists of a disk or plate, of any suitable material,having two or more arms projecting from the sides of the same, andconstructed and adapted .for attachment to a jar having ribs-0rprojections at the outside of the neck, as fully described hereafter;the said cap being cheap, durable, and eflicicnt.

In order to enable others skilled in the art to make and use myinvention, I will now proceed to describe its construction andoperation, reference being had to the accompanying drawing, which formsa part of this specification, and in which- Figure 1 is an exterior viewof a preserve jar with my improved cap.

Figure 2. a vertical section.

Figure 3, a plan view of the cap; and

Figure 4, a modification.

A is a jar, and B is a cap, which, in the present instance, consists ofa thin metallic disk orplate, stamped to the proper form, and having anannular recess at the under side for the reception of a gum ring, 2',the latter hearing on the upper edge of the neck of the jar. Atoppositcsides of the cap B are curved arms 6 I), the lower end of each of whichprojects inwards beneath an inclined rib or projection, c, on theoutside of the neck of the jar, and between the ends of the adjacentribs are recesses y. When the jar is to be sea-led, the cap is broughtover the same, and is depressed until the gum ring irests on the upperedge of the neck, thearms b b passing through the recesses 3 The cap isnow turned in the direction of its arrow, fig. 3, when the ends of thearms!) 6 will be brought beneath and in contact with the inclined loweredges oi the ribs 0 0, so that the cap is drawn downwards, and the gumring 1' is so compressed between the cap and the jar asto'eifectuallyprevent the passage of air between them. When the jar isto be unsealed, the cap is turned back until the arms I: b are oppositethe recesses y 1/, and is then removed. The disk and its arms mayconsist of a single piece of cast or malleable iron or other-metal, orof wood or other suitable material; inclincd recesses may also besubstituted for-.the inclined ribs 6 Z) on the neck of the jar. In themodification shown in fig. 4, the arms 6 6, instead of being curvedinwards, are inclined to one side, so that when their upper inclinededges are brought beneath projections on the jar the cap will be drawndownwards. The number of arms 6 and ribs cmay be increased, if desired;the gum ring i also, instead of fitting in a recess in the cap, may reston a shoulder, or in a recess, at the edge of the neck of the jar.

' I claim as my invention, and desire to secure by Letters Patent A cap,consisting of a. disk, B, and arms 6 b, the whole being constructed andadapted for attachment to a "jar, substantially as described.

In testimony whereof I have signed my name to thisspecification in thepresence of two subscribing witnesses.

JOSEPH BORDEN.
